docker安装datax-web3.0.1(继承了datax和datax-web) 和 安装过程中遇到的问题_linshellfeng/datax_web:3.0.1

最近做项目需要用docker部署datax和datax-web,在网上找到了一个镜像linshellfeng/datax_web:3.0.1，该镜像封装了datax和datax-web。

可以用docker search datax_web搜到

1. 安装前准备：安装mysql,mysql数据库里建立数据库datax_web,数据库datax_web里建立data-web软件需要的表（建立表的sql需要用官方提供的）

在安装datax-web之前需要先安装mysql数据库，安装过程就不再赘述，下面是安装好数据库后建立数据库和表的步骤以及遇到的一些问题。

#建立数据库datax_web
create database datax_web;
use database datax_web;
#datax-web.sql文件见下一个代码骗
source datax-web.sql
#添加用户root，13456处是自己设置数据库的密码
create user 'root'@'%' identified with mysql_native_password by '123456';
#赋予用户操作数据库datax_web的权限
grant all privileges on datax_web.* to 'root'@'%';
flush privileges;

下面是一些关于使用mysql数据库的一些小问题
**问题一：**在使用docker封装的mysql时候第一次登录可能会报如下错误：

解决办法是：第一次登录 ：mysql -h 127.0.0.1 -P 3306 -u root -p
问题二：

解决办法是：删除原来的用户并重新创建用户，然后赋予用户操纵数据库的权限：

#删除原来的用户
drop user root@'%';
#创建新的用户
create user 'root'@'%' identified with mysql_native_password by '123456';
#赋予新用户操纵数据库的权限
grant all privileges on datax_web.* to 'root'@'%';

拉取镜像，修改配置文件，访问UI端口

#拉取镜像
docker pull linshellfeng/datax_web:3.0.1
#运行容器
docker run -d --name datax-web -p 9527:9527 linshellfeng/datax_web:3.0.1
#进入容器
docker exec -it datax-web bash
#进入容器后修改配置文件bootstrap.properties
#配置文件的目录：/home/datax/datax-web-2.1.2/modules/datax-admin/conf
#配置文件中的内容示例如下图，各属性解释如下：
#数据库所在主机的IP地址
DB_HOST=10.109。246.136
#数据库端口号
DB_PORT=3306
#数据库用户名
DB_USERNAME=root
#数据库用户密码
DB_PASSWORD=123456
#数据库的名称
DB_DATABASE=datax_web

datax-web中数据库的配置信息如下图，根据自己实际情况做修改：

然后就可以访问9527端口,地址如下（需要将10.109.246.190改成自己的IP地址）：
http://10.109.246.190:9527/index.html
默认的登录用户和密码如下：
用户名：admin
用户密码：123456
访问截图如下：
